Abstract Mosaikjungfer. Die Libellenlarve fängt Beute durch Vorschnellen des Labiums nach vorheriger orientierender Einstellbewegung. Der Fangschlag des zu einer Fangmaske umgebildeten Labiums besteht aus fünf unterschiedlichen Bewegungsphasen. Fressen eines Wurmes. Mit Zeitdehnung.
Southern Aeschna. The dragonfly larva captures prey with a rapid strike-like movement of its labium; this follows a previous orientation movement. The capture-stroke of the labium, which has been transformed into a clawed mask, consists of 5 different phases of movement. Larva eating a worm. With slow-motion.
